MACHINE FOR FORMING TILES.

SPECIFICATION formingpart of Letters Patent No. 682,667, dated September 1'7, 1901.

Application filed September 25, 1900. Serial No. 31,043. (No model.)

To all whom it may concern:

Be it known that I, PAUL BRUNS, manufacturer, a citizen of the Kingdom of Prussia, and a resident of Hanover, Germany, (whose post-office address is Grosse Pfahlstrasse 7 1,) have invented certain new and useful Improvements in Machines for Forming Tiles, of which the following is a specification.

The object of this invention is a mechan' ical forming-table for profiled tiles. By aid of this forming-table tiles possessing great strength and homogeneousness are produced owing to the great pressure exerted upon the forming-tools and the raw material.

In the accompanying drawings, Figure 1 shows the forming-table cut lengthwise according to line B B of Fig. 2, Fig. 2 showing a cross-cut according to line A A of Fig. 1.

The frame a carries the form-chest I). Below this two rails c are arranged, which serve as guides for the feeding-box cl. The bottom of this feeding-box is formed by a shutter e, which is fastened to two arms f, linked to the side walls of the box, which carry the axles g of a profiled roller h. This roller turns in the interior of the feeding-box and serves to drive the material into the forming-chest and to exert a shaping and pressing influence upon it. The motion of the feeding-box from its initial position toward the forming-chest and above same is effected by aid of a handlever 10, linked tothe frame a. by aid of a pin Z. Its shorter arm is linked to a connectingrod movably fastened to the pin a, projecting from an extension 0 of the feeding-box d. Therefore by lifting the hand-lever is from the horizontal to a vertical position thefeedconnected with each other and running loose on their axles. Above the smaller one, p, a

fastened to it, to another toothed wheel, 8', fixed to the axle of the roller h. Therefore by pulling the feeding-box by aid of the handlever 7c forward and backward the roller his caused to rotate inside the feeding-box. At the same time the roller by aid of a piniongear u'v causes the rammert' to oscillate about a horizontal pivot t, fastened to the side walls of the feeding-box. The rammer is eccentrically connected with the pinion 1;, so that the rotating motion of the latter causes the rammer c' to go up and down like a bookcover,thus exerting at the same time a smoothing and aramming action upon the material contained in the forming-chest. The hand lever lc exerting a strong downward pull upon the feeding-box and the forming-tool inside the latter, the material is subjected to a strong pressure, favoring a great homogeneousness, and increased strength of the tiles produced. The shutter e, closing the feeding-box at the bottom, is'arranged to open as soon as the feeding-box passes over the forming-chest, the front edge of the shutter being held back by the latter. On the feeding box being pushed back to its former position the shut-- ter is closed automatically by aid of its own weight. The formed tile is ejected from the forming-chest by aid of a tread-lever device to of well-known construction.

In a forming-table for profiled tiles and the like the combination of a frame, rails being disposed in said frame, a forming-chest reposing on the frame between said rails, a feeding-box slidable on said rails, a pin fastened to an extension of said feeding-box, a lever fastened to the side of said frame, a connecting-rod linked on one side to said lever and on the other side to said pin, a profiled roller, a rammer arranged inside the feeding-box, gearing for operating same, and a rack fastened to the frame, substantially as shown and described.

2. In a forming-table for tiles and the like the combination with the feedingebox, the

roller and rammer inside said box and the pin fastened to the extension of said box, of
